OpeRaTINg THIS TOOL.
• Always operate, inspect and maintain this tool in accordance with
American National Standards Institute Safety Code of Portable Air Tools
(ANSI B186.1) and any other applicable safety codes and regulations.
• For safety, top performance and maximum durability of parts, operate this
tool at 90 psig 6.2 bar max air pressure with 3/8" diameter air supply
hose.
• Always wear impact-resistant eye and face protection when
operating or performing maintenance on this tool. Always
wear hearing protection when using this tool.
• High sound levels can cause permanent hearing loss. Use
hearing protection as recommended by your employer or
OSHA regulation.
• Keep the tool in efficient operating condition.
• Operators and maintenance personnel must be physically able to handle
the bulk, weight and power of this tool.
• Air under pressure can cause severe injury. Never direct air
at yourself or others. Always turn off the air supply, drain
hose of air pressure and detach tool from air supply before
installing, removing or adjusting any accessory on this
tool, or before performing any maintenance on this tool.
Failure to do so could result in injury. Whip hoses can cause
serious injury. Always check for damaged, frayed or loose
hoses and fittings, and replace immediately. Do not use
quick detach couplings at tool. See instructions for
correct set-up.
• Air powered tools can vibrate in use. Vibration, repetitive motions or
uncomfortable positions over extended periods of time may be harmful to
your hands and arms. Discontinue use of tool if discomfort, tingling feeling
or pain occurs. Seek medical advice before resuming use.
OPERATION
• Always use the recommended wheel guard to prevent
injury from broken grinding wheel parts. If a guard has
withstood a wheel breakage, discontinue its use and
replace it with a new guard. It may be damaged. Position
the guard between the grinding wheel and the operator.
Use barriers to protect others from wheel fragments and grinding sparks.
• Always wear impact-resistant eye and face protection when involved in
the operation of this tool. Even small projectiles can injure
eyes and cause blindness. A grinding wheel that bursts
can cause very serious injury. Daily measure the air grinder
speed with a tachometer to make sure it's not greater than
the RPM marked on the grinding wheel. Never use a
grinding wheel marked with a speed lower than the air grinder speed.

• Place the tool on the work before starting the tool. Do not point or indulge
in any horseplay with this tool.
• Anticipate and be alert for sudden changes in motion during start up and
operation of any power tool.
• Correct grinding wheel mounting is necessary to prevent injury from
broken wheels. Do not use chipped or cracked grinding wheels. Grinding
wheels should be a free fit on the spindle to prevent stress at the hole.
Use only wheel collars that come with the grinder for mounting the
grinding wheel. Flat washers or other adapters may over stress the wheel.
Always use heavy paper blotter discs between the wheel collars and the
grinding wheel. Tighten the wheel on the spindle to prevent spin off when
the air grinder is turned off.
• Do not lubricate tools with flammable or volatile liquids such as kerosene,
diesel or jet fuel.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace any damaged labels.
• Use accessories recommended by Matco Tools.
• Before grinding, test grinding wheel by briefly running the tool at full throttle.
Be sure to use a barrier (such as under a heavy work table) to stop any
possible broken wheel parts.
To Assemble Grinding Discs:
1. Use #46 stop spanner to hold spindle #36.
2. Place #43 washer on #36 spindle.
3. Place #44 grinding disc wheel over #36 spindle.
4. Screw on disc nut #45, shoulder side facing tool. Secure tightly!
2
• Slipping, tripping and/or falling while operating air tools can
be a major cause of serious injury or death. Be aware of
excess hose left on the walking or work surface.
• Keep body working stance balanced and firm. Do not
overreach when operating the tool.
• Do not carry tool by the hose. Protect the hose from sharp
objects and heat.
• Tool shaft may continue to rotate briefly after throttle is
released. Avoid direct contact with accessories during and
after use. Gloves will reduce the risk of cuts or burns.
• Keep away from rotating end of tool. Do not wear jewelry or
loose clothing. Secure long hair. Scalping can occur if hair
is not kept away from tool and accessories. Choking can
occur if neckwear is not kept away from tool and
accessories.
